ANCHOR FOR FLOOR SLEEPERS.

Application filed April 8,

ing and fastening means in a durable unitary structure.

An illustrative embodiment of this invention is shown in the accompanying drawing, wherein Figure 1 is a vertical fragmentarysection of a concrete slab to which a sleeper is se cured by an improved anchor, the dotted outlines representing the fastening means in their operative positions.

Fig. 2 is a perspective showing a sleeper secured to a slab by the improved anchoring devices.

Fig. 3 is a fragmentary perspective of one of the devices.

In the specific form shown, the improved anchors are used for supporting floor sleepers 1 on a concrete slab 2. Floor sleepers are usually disposed in substantially parallel spaced relation to form a wooden frame structure to which the customary floor boards are nailed. The usual spacing of the sleepers is twelve or sixteen inches between centers. The sleepers may also vary in thickness and they are used generally in sizes ranging from two to four inches in width. For this reason it has been necessary for the manufacturer to carry in stock a large supply of sleeper anchors of various sizes to accommodate the different sizes of floor sleepers.

In the construction herein illustrated, the anchor includes supporting means arranged to provide a seat which is adjustable in width so that one such anchor may be used for supporting sleepers of various sizes.

The improved anchoring device is preferably made of wire which is sufficiently flexible to permit bending of the fastening portions into engagement with the sleepers and to permit adjustment of the seat portion.

In the construction illustrated, each of the devices comprises a plurality of anchoring members 8 of substantially identical form, disposed in substantially parallel planes and the concrete.

rigidly secured to a pair of spacing elements 4, which space the members 3 at regular intervals along the sleeper. In the form showmeach of the members comprises a substantially V-shaped. anchoring portion 5 adapted to be embeddedin The upper ends oi'the anchoring portion 5 are bent to provide a pair of arms 6 extending in respectively opposite directions to form a seat 7 adapted to support the sleeper. The arms (3 are flexible so as to be adapted to be bent transversely. to the seat 7 for en'ibracing the sleeper. Formed'at the extremities of the arms 5, are eyelets 8 forreceiving nails 9or other suitable fasteners driven into, the sides of the sleeper. r a

The spacing. elements 4 are preferably wire rodsof'the same gauge as themembers 3. The elements 4 are disposed in substantially parallelspaced relation on respectively opposite sides ofthe anchoring portions 5, and are preferably welded to. the arms 6 directly below, the seat portions 7. v

1th this improvedyfornr and arrangement ofparts, the width of the seat portions 7 may be adjusted by expanding or contracting the anchoring portions 5.

In operation, after the concrete has been poured and before it has set, the improved anchoring devices are placed in'the. slab as shown in full outline in Fig. 1. After the concrete has set, the sleepers are placed on the seats 7 and the arms 6 are then bent upwardly to embrace the sleepers and to permit the nails to be driven into the sides of the sleepers.

Although but one specific embodiment of this invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of thisinvention as defined by the following claims.

I claim:

1. A device of the class described comprising a plurality of substantially identical members having anchoring portions adapted to be embedded in a. support, a pair of substantially parallel spacing elements rigidly secured to saidmembers, said 1116l11 bers having seat portions for supporting a bar extending longitudinally of said spacing element, and fastening portions arranged on respectively opposite sides of said seat portions and adapted to embrace the bar.

2. A device of the class described comprising a plurality of substantially identical members having anchoring portions adapted to be embedded in a support, a pair of substantially parallel spacing elements rigidly secured to said members, said members having seat portions for supporting a bar extending longitudinally of said spacing elements, said anchoring portions being adjustable to vary the width of said seat portions for accommodating bars of various sizes, and fastening portions arranged on respectively opposite sides of said seat portions and adapted to embrace the bar.

3. A device of the class described comprising a plurality of substantially identical members having anchoring portions adapted to be embedded in a support, a spacing element rigidly secured to said members, and arms on said anchoring portions extending in respectively opposite directions to form seats for supporting a bar extending longitudinally of said spacing element, portions of said arms being bent transversely to said seats to embrace the bar.

4. A device of the class described comprising a plurality of flexible Wire members having anchoring portions adapted to be embedded in a support, a pair of substantially parallel Wire spacing elements Welded to said members, and a pair of arms on each of said anchoring portions extending in respectively opposite directions to form a seat for supporting a bar arranged longitudinally of said spacing elements, portions of said arms being adapted to be bent transversely to said seat to embrace the bar.

5. A device of the class described comprising a plurality of flexible Wire members having substantially V-shaped anchoring prising a plurality oi flexible \vire members havin substantiallv V-slia )ed liIlCllOl'lll" h .1 b portions, the legs 0t each ot said anchoring portions being bent to provide a pair of oppositely extending arms prmiding a seat adapted to support a bar, the. ends of said arms being adapted to be bent at substantially right angles to said seat for embracing the bar, and a pair of substantially parallel spacing elements rigidly secured to said arms and arranged on respectively opposite sides of said anchoring portions.

7. A device of the class described comprising a plurality of flexible WiIQ members having substantially V-sliaped anchoring portions, the legs of each of said anchoring portions being bent to provide a pair of oppositely extending arms providing a seat adapted to support a bar, said anchoring portions being adjustable for varying the Width of said seats to acconnnodate bars of various sizes, the ends of said arms being adapted to be bent transversely to said seats for embracing the bar, and a pair of substantially parallel Wire spacers Welded to said arms and disposed on respectively opposite sides of said anchoring portions.
